, fgylnventor Witness s idiom eys tubing, and that said sinkers, of which any desired number may be employed, practically constitute a rigid rod which, without ob structing the pu1np-tubing,will be very eiii cient for the purpose set forth. The pres? ence of these sinkers is necessitated by the substitution. for the. rigid pump-rods usually employed of the flexible member 21. :The ad vantages of using" the latter are numerous and will be readily appreciated by those who are practically acquainted with the artwith whichthis invention isassociated. The or dinary pump-rods are constructed in lengths or sections which have to be laboriouslyconnected' as the piston is being inserted into the well, or disconnected when it is desired to remove the piston from the well; The exsuilicient width to formi a friction-surface,

pause and delay of this labor'may be entirely dispensed with under mypresent. invention, which. permits the piston to-be raised-or lowered by simply winding the flexible member 21 upon a reel, as will be presently more fully described. The initial expense i's-also very muchlessthanthat of pump-rods of the kind heretofore usually employed. a

The pumping mechanism proper frame or stand, which has'been illustrated as being composed of two tubular uprights 30, the lower ends of which may be sunk into the ground, although theyfare preferably set in a cement or concrete foundation, brace-rods 3-]. being employed to'make the construction exceedingly durable and firm, The upper ends of .the uprights 30 have bearings for a transverse shaft 32, carr'yinga reel 33, one

flange of which is provided. with a tread of which is engaged. by a flexible friction-brake 34. The brake-operating means are not shown in detail, but the construction thereof 7 is well-understood. One end of the shaft 32, v carries a s rocket-wheel 35, which is connected by a 0 rain 36 with the source of power. The othenend'of the. shaft 32 carries a -crank 37 providedwith a plurality of apertures 38 at. various distances from the axisof the shaft 32', said apertures being forthe reception of.

be locatedintermediately between two wells,

- each equipped inv the manner herein dev to be utilized for pumping twowells.

scribed, and the flexible operating member 19 of each being extended-to the wrist-pin 38, thus enabling a single operating mechanism It is furtherv evident that other means than a chain and sprocket may, if desired, be employedforj transmitting motion to the shaft includes a.-

eeaeee 32 from the source of power, which-latter'may be a motor or engine of any desciription h The operation of this invention will be readily understood from the foregoing-dc? scriptionj taken in connection with the draw: 'ings. Thestroke'o'f the pump is regulated by the distance of thewrist-pin 38 from the axis of the shaft 32, the stroke being in creased by increasing the distance between the wrist-pin and the axis of the shaft.

is 1" the latter revolves, the flexiblemember 3.9,

'operatingunder' the pulley and" over the l with; -When saidmember is hoisted, the

valve is raised and the tubulalymember 11',

- pulley 16, will alternately hoist and lower the flexible member 21, which is connected there.

which is connected with the flexible member 21 and which operates as'a guide or polish rod, is likewise elevated. On the downward movement of the flexible member 21 the piss ton is lowered into the well by the sinl-zers connected therewith. The liquid being forced upwardly through the well-casing by the operationof the piston escapes through the tubular member 11 and its branch 12. In the event of stoppage of the lead-pipes,

caused by freezing or-by obstructions of any kind, the liquid being forced upwardly into the well-tubing will force or flea-t the tube 11- in an upward direction, thus indicating to the operator the existing trouble and enabling the pumping machinery to be stopped before damage'can be done. This feature of the in vention is considered to be one of great inn portance, inasmuch as it oftentimes happens that one or more sections of a-well tubing are split by the continued forcing of liquid while the pipes are obstructed. In such case it is sometimes found necessary to draw a corn sider-able portion of the well tubing before ,theinjured section of said tubing can be reached and repaired or a new one substi tute'd;

When it shall be desired to withdraw the piston from the well, the flexiblemembers 19 and 21 are disconnected and the latter, after being guided over the pulley iii-and? under I:

the pulley 15, is oonnecteddirectly with the reel; Thetube11isalsoobviouslydetachedl By simply winding the-flexible member 21 upon the reel'the piston may bevery easily and quickly extracted from the well.

' p The operating i'nechanism-hereindescribed maybe utilized for other purposes than those I herein 1nd1eated*+for instance, for the purpost of withdrawing thewell-tubinglin which-latter event a derrick ofordinary conl struotion will be erected over the well and furnished withclamping mechanism, such as is well known iii-this connection.

When ordinary pump-rods are used-in lieu of the flexible: member herein-described; the" apparatus. may also be usefully employed for Withdrawing such rods, as will be readily un- I derstood: a

By the use of the flexible member 21, as herein described, in lieu of the ordin ary pumprods I find-thatthe accumulationof ,rod

wax or paraffin in the well is largely pre-' vented, and necessity for frequently cleaning out the well is thus obviated. I Having thus described the invention, what is claimed is 1 A head member mounted securely upon the upper end of a well-tubing, a frame including top and bottom plates clamped upon said isv head and positively secured thereby against;

upward and downward movement, said uper plate being provided with upwardly and orwardly extending brackets, guide-pulleys operating flexible member guided over said pulleys and into the Well-tubing.
